Specification of Letters Patent.

Patented Oct. 17, 1905.

Application filed April 6, 1905. Serial No. 254,098.

To tl/f v/'mm ift may concern.:

Be it known that I, ORLANDO C. Moons, a citizen of the United States, and a resident of Morrow, in the county of Vai-ren and State of Ohio,have invented a new and Improved Husking-Machine, of which the following is a full, clear, and exact description.

My invention relates to corn-huskers, it being more particularly directed to the feed mechanism for the snapping-rolls.

Aln liusking-machines if the movable snapping-roll is set with comparatively light tension it may permit smaller ears to pass without removal and is liable to shell olil much of the corn. It is therefore desirable to apply considerable pressure, which insures the perfeet snapping of the ears; but when this .is done it renders automatic feeding practically impossible, since it becomes difficult for the stalks to enter between the snapping-rolls, and they frequently catch and choke the feed. This is fatal to satisfactory operation, which is dependent upon a substantially uniform regular passage of the material between the snapping-rolls. lf it were otherwise, it would require the constant attention of an operator to back off the choked feed, or that which failed to enter, and again start it forward.

To obviate these difliculties and to provide a mechanism which will allow the applying of the proper pressure to the snapping-rolls and at the saine time secure automatic feed is the principal object of my invention.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a top plan view of the feed end of a husking-machine to which one embodiment of my invention is applied. Fig. 2 is a vertical longitudinal section therethrough on the line 2 2 of Fig. 1. Fig. 3 is a transverse vertical section on the line 3 3 of Fig. 2. Fig. L1 is a detail in side elevation of a portion of the driving-gearing; and Figs and are enlarged sectional details on the lines 5 5 and 6 6, respectively, of Fig'. 2.

Journaled in fixed bearings in a frame 10 is a rotatable drum 11, over which operates a feeding belt or member 12. This is shown as consisting of parallel belts connected by crossslats and serves to convey the stalks to the husker and assists in effecting their introduction. Above the belt is a companion feeding member in the form of a rotatable grooved roll 13, the journals of which turn in boxes 14 14 capable of vertical movement in ways carried by the frame.

In the frame in advance of the feed ing members is journaled a stationary snapping-roll 15 and a bodily-movable companion roll 16. The bearings 17 of this movable roll are mounted in arms 18 18, swinging' about the shaft of the drum 1l and being connected to move together by a bar 19. Springs 2O contact with the arms and with the frame and serve to hold the roll 16 in contact with its companion. The pressure of the springs may be adjusted b v screws 21, threaded through the upper portion of the frame. Beyond the snapping-rolls the frame carries the usual rotatable shredding-cylinder, (not showin) to the shaft of which power is applied. It has rotating with it a gear 9.2, which meshes with a gear 2.3 upon the shaft of the stationary snappingroll. This has rotating with it a pinion 211, meshing with an idle pinion 25, which drives a gear 26 upon the shaft of the drum 11. This train of gearing provides for lthe rotation of the lower siiappingioll and the travel of the feed-belt in the same direction. Upon the opposite end of the drumshaft is fixed a gear 27, engaging a pinion 98 upon the shaft of the upper snapping-roll to rotate this in the opposite direction from its companion. It should be noted that the mounting' of this bodily-movable snappingroll upon the rigidly-connected arms not only maintains it throughout its length in the proper relation to the lower roll and causes both springs to be uniformly effective, but also permits the pinion .28 to swing about the gear 27 in such a manner that a proper meshing of the teeth will be secured through the entire range of movement of the upper roll. The feedroll 13 is shown as turned in a direction opposite to the travel of the belt by siiirocket-gearing 29, connected with the shaft of the upper snapping-roll.

Each of the arms 18 has beyond the bearing 17 an extension 30, projecting into thel lower end of a slot 31 in a link 3Q. Each of these links depends from the inner end of a lever 33, which has an adjustable fulcrum consisting' of a box 34. which may be moved longitudinally of the lever, trunnioned in a bracket 35. Each bracket, as illustrated, is clamped in place by bolts 36, passing through slots 37 in the horizontal members of the frame. i lt will be seen that the movement of these fulcrum-boxes toward and from the links will vary the strokes of the latter, the

nearer the boXes approaching' to the links thek shorter their travel. Upon the outer end of each of the levers is shown a roll 38, which contacts with a cam 39, fixed upon ashaft 40, extending transversely of the frame and being' rotatable therein. Each of the cams comprises a portion concentric to the axis (designated by 41) and a recess 42 of sufiicient size to admit a portion of the periphery of the roll. The shaft 40 is preferably mounted in independently-movable standards 43, which may be secured in place by bolts 44, extending through vertical slots 45. This permits the cam-shaft to be adjusted toward and from the rolls to control the initial positioning' of the upper snapping-roll. Fast upon the shaft 40 is an arm 46, which is connected by a rod 47 with an arm 48 upon a transverse shaft 49. This shaft 49 also has at each side of the arm 48 an arm 50, from which depends a link 51, which links at their lower ends are articulated to the shaft of the roll 13.

The material being placed upon the conveyer-belt is advanced by it to the verticallymovable feeding-roll, which is raised, and through the intermediate arms and connecting-rod rotates the cam-shaft. The rolls of the levers 33 normally lie in the cam-recesses, and at this time the snapping-rolls are in contact, the ends of their carrier-arms being' at the bottoms of the slots in the links 32. As the cam-shaft is rotated the lever-rolls immediately ride out of the recesses and through this lever-and-link system raise the upper snapping-roll from its companion a sufiicientdistance to give the proper gripping angle. This occurs -just at the moment that the ends of the stalks are presented to the snapping-rolls, which therefore readily enter between them and are operated upon. After the lever-rolls have once left the recesses they are upon the concentric portions of the cams, so that the automatic separation of the snapping-rolls is notincreased no matter how large quantities of the material pass between them. It should be noted that at all times the snapping-roll springs are capable of exerting' their full pressure and that the movement of the upper roll is not interfered with, the extensions of its supporting'- arms being free to rise through the slots in the links 3Q. If the character of thematerial fed is such that it is desirable to secure a greater or less initial separation of the snapping-rolls, the operator has only to move the lever-fulcrums toward or from therolls, thus varying' the. effective throw. This arrangement allows the use of such spring-pressure upon the uppersnapping-roll that certain action may be secured, since the automatic separation obviates any possibility of afailure of the material fed to be properly engaged.

Having' thus described myinvention, I claim as new and desire to secure by Letters Patenti 1. In a husking-machine, the combination with rotatable feeding members movable toward and from one anotheryof separable snapping-rolls, and means wherebythe snapping-rolls are separated upon the movement of the feeding' members.

In a husking-machine, the combination with movable feeding' members, of rotatable snapping-rolls, one of which is bodily movable, a lever system connected with the bodily-movable roll, a cam rotatable by the movement of a feeding member and coperating' with the lever system, and means for permitting the snapping-roll to move independently of the lever system.
